Why are my gums red around my teeth
Red gums around a tooth usually indicate local inflammation from plaque, but trapped food, trauma, decay, or infection can produce similar redness.
Why are your gums red around one or more teeth?
Red gums around a tooth usually indicate local inflammation from plaque, but trapped food, trauma, decay, or infection can produce similar redness.
The gum may look red because inflamed blood vessels are closer to the surface and the tissue is swollen.
How can plaque at the gumline cause localised redness?
Plaque at the gingival margin can inflame the surrounding gingiva. Redness limited to one tooth may also reflect a rough filling, food impaction, a cavity near the gumline, a cracked tooth, or an abscess.
What can you do when redness surrounds a tooth?
Brush the area gently, clean between the teeth, and check for food caught beneath the gum edge. Do not cut, squeeze, or repeatedly probe the red tissue.
When does redness around a tooth need dental assessment?
Arrange an examination if redness lasts, bleeds, hurts, enlarges, or is associated with pus, a bad taste, tooth sensitivity, looseness, fever, or facial swelling.
Is the redness limited to the gum or linked to the tooth root?
Is the redness confined to the gum or connected to the tooth root? Ask whether the filling, gum pocket, tooth nerve, or bite needs testing and whether a radiograph is indicated.
Frequently asked questions
Can a red gum heal on its own?
Mild plaque irritation may settle with thorough gentle cleaning, but persistent or localized redness needs assessment for a deeper cause.
Why is one gum area red after a filling?
A rough or overhanging filling, altered bite, trapped food, or unrelated inflammation can irritate the area and should be checked.
